I-Fiberglass rebar,kwaziwa njengeI-GFRP (i-Glass Fiber Reinforced Polymer) rebar,yindlela yokusebenza ephezulu yokuqinisa intsimbi yendabuko esetyenziselwa ukwakhiwa. Ibonelela ngeenzuzo ezininzi, kubandakanywa ukumelana nokugqwala, umlinganiselo ophezulu wokuqina kobunzima, kunye nokungaqhubeki kombane, okwenza ukuba ifaneleke ngokukodwa usetyenziso kwiindawo ezibuhlungu kunye nezakhiwo ezifuna ubomi obude benkonzo. Inkqubo yemveliso yokujikai-fiber yeglasi yokujikelezakwii-fiberglass rebaribandakanya amanyathelo angundoqo aliqela, ekukhetheni okufanelekileyoi-fiber yeglasi yokujikelezaukuya kukwenziwa kokugqibela kwe-rebar ngokwayo.

Inkqubo yemveliso iqala ngokukhethwa kweukujikeleza i-fiber yeglasi,eyingqokelela yeefilaments zeglasi eziqhubekayo. Ukukhetha ukuzulazula kubalulekile ekumiseleni iipropathi zomdlalo wokugqibelai-fiberglass rebar. I-E-glass, eyi-alkali-free glass formulation, isetyenziswa ngokuqhelekileyo ukuvelisai-fiberglass rebarngenxa yokuhambelana kwayo ne-polymer matrices kunye nokukwazi kwayo ukunika amandla aphezulu kunye nokuqina. I-E-glass roving, kunye neyunifomu yayo kunye neefilaments eziqhubekayo, iba yinto ephambili ekrwada kwinkqubo yokuvelisa.

Kanye xa kufanelekilei-fiber yeglasi yokujikelezaikhethiwe, iphantsi kothotho lwezigaba zokuqhubekekisa ukuyiguqulelai-fiberglass rebar.

Inkqubo yemveliso ibandakanya la manyathelo alandelayo:

ULungiselelo lwe-Roving: I-glass fiber roving iyahlolwa, icociwe, kwaye igqunywe ngento yokulinganisa, ephucula ukuncamathela phakathi kweentsinga zeglasi kunye ne-polymer matrix eya kuthi kamva ivale i-rebar. Ukulinganisa kwakhona kunceda ukukhuselaimicu yeglasiukusuka kwi-abrasion kunye nokuphathwa ngexesha lamanyathelo okucubungula alandelayo.

INdibano kunye noLwakhiwo: Imicu emininzi yeiglasi egqunywe ngefiber rovingziyadityaniswa kwaye zitsalwe kwibhafu yeresin ukuze zimiliselwe ngentlaka yepolymer, ngokuqhelekileyo ipolyester okanyevinyl ester. I-rovings emiliselweyo itsalwa ngedayisi yokubumba ukwenza i-rebar enqwenelekayo yedayamitha kunye nokumila.

Ukunyangwa kunye nokuqinisa: Ukubunjwai-fiberglass rebaremva koko iphantsi kwenkqubo yokunyanga, apho i-polymer resin ingena kwi-chemical reaction ukuze iqiniswe kwaye idibanise kunye nemicu yeglasi, ekhokelela kwi-composite material eyomeleleyo kwaye ehlala ixesha elide.

Ukusika kunye nokuPakisha: Emva kwenkqubo yokunyanga, ii-fiberglass rebarisikwe kubude obufunwayo kwaye ipakishwe ukuze isasazwe kwiindawo zokwakha kunye nabavelisi ukuze basetyenziswe kwizicelo zokuqinisa ikhonkrithi.

Iinzuzo ze-fiberglass rebar

Iinzuzo zei-fiberglass rebarphezu kokuqinisa intsimbi yesintu zininzi kwaye zibalulekile. Okokuqala,i-fiberglass rebarinika uxhathiso olukhulu ekudlekeni, oko kuyenza ilungele imeko apho isithinteli sentsimbi sinokuwohloka ngokuhamba kwexesha, njengezakhiwo zaselwandle, izibonelelo zokusetyenzwa kweekhemikhali, kunye neziseko zophuhliso kwimimandla eselunxwemeni. Iimpawu zayo ezingezizo zokuqhuba nazo zenza ukuba zilungele ukusetyenziswa kwiindawo zombane kunye ne-MRI-sensitive.

Ngaphezu koko,i-fiberglass rebar'samandla aphezulu-to-ubunzima ratio iququzelela ukuphathwa lula kunye nofakelo, ukunciphisa umsebenzi kunye nexesha elifunekayo kwiiprojekthi zokwakha. Ubume bayo obukhaphukhaphu bukwayenza ilungele usetyenziso apho ukuncitshiswa kobunzima bobume bubonke kuyinkxalabo, njengakwiidekhi zebhulorho kunye nokubuyiselwa kwenyikima.

Ukongeza kwiimpawu zayo zomzimba,i-fiberglass rebarinika ubomi benkonzo ende kunye neemfuneko zogcino ezincinci, igalelo ekomelezeni nasekuzinzeni kwezakhiwo zekhonkrithi ezomeleziweyo. Ikwabonelela ngokuguquguquka koyilo, ukuvumela ukulungelelaniswa koyilo lokuqinisa kunye nokufezekiswa kwezisombululo zoyilo lwezakhiwo kunye nobunjineli.

Isishwankathelo, inkqubo yemveliso yokuguqulai-fiber yeglasi yokujikelezakwii-fiberglass rebarkubandakanya ukukhethwa ngononophelo kunye nokulungiswa kwemathiriyeli ekrwada, kunye nokudityaniswa ngokuchanekileyo, ukufakwa kunye neenkqubo zokunyanga. Isiphumoi-fiberglass rebarinika iingenelo ezininzi ngaphezu kokuqiniswa kwentsimbi yemveli, kubandakanywa ukuxhathisa ukubola, umlinganiselo ophezulu wamandla-kubunzima, ukungabikho kwe-conductivity, kunye nokuqina kwexesha elide, okwenza kube yindlela enyanzelisayo yoluhlu olubanzi lwezicelo zokwakha.
